1 ## 2 # This file is used to document mismatches between Intel Platform Innovation Framework specification 3 # (http://www.intel.com/technology/framework/spec.htm) and data structures defind at IntelFrameworkPkg 4 # package in EdkII Open Source Project (https://edk2.tianocore.org/source/browse/edk2/trunk/edk2/IntelFrameworkPkg) 5 ## 6 7 ## 8 # The general consideration about keeping the mismatches in EdkII: 9 # 1. Some definitions defined in Framework specification may bring a little complexity on implementation. EdkII 10 # makes changes on them from the view of code development. 11 # 2. Some definitions are NOT defined in Framework specification, but introduced in Edk. EdkII chooses to keep 12 # them for backward-compatibility. 13 # 3. The name of some definitions are NOT consistent with Framework specification. If the name doesn't bring 14 # misunderstanding literally, EdkII chooses to keep them for backward-compatibility. 15 # 4. Some defintitions don't exactly match Framework specification, some new field members are introduced in EdkII 16 # to reflect the latest industry standard. 17 # 18 # Note: 19 # The IntelFrameworkPkg contains Framework specification contents that were not adopted by UEFI/PI, and names may be 20 # changed (such as adding "FRAMEWORK_") to avoid name collisions with approved UEFI/PI specifications. 21 ## 22 23 ## 24 # Mismatch with Intel Platform Innovation Framework for DataHubSubclass Specification (Version 0.90) 25 ## 26 1.
